Color3 value gets set to 0,0,0. How do I fix this?

I'm probably making an obvious mistake here, but I've tried lots of different routes to try and solve this problem, none of which have worked.

My script is:

local colourSave = game:GetService("DataStoreService"):GetDataStore("vehicleStats")
local key = ""
local Colour = Color3.new(127/255,127/255,127/255)

game.Players.PlayerAdded:connect(function(plr)
    key = "player_"..plr.UserId
    local initCheck = colourSave:GetAsync(key)
        if initCheck == nil then
            colourSave:SetAsync(key,tostring(Colour))
        end
    wait(1)
        for i, v in pairs(game.Workspace.ViewModel.Ranger.Body.Paint:GetChildren()) do
            v.Color = Color3.new(colourSave:GetAsync(key))
        end
            print(Color3.new(colourSave:GetAsync(key))) --debug
end)

game.ReplicatedStorage.vehicleStats.flashColour.OnServerEvent:connect(function(player, colour)
    colourSave:SetAsync(key,tostring(colour))
end)

The "colour" parameter received from the flashColour remote event looks something like this: 0.84532, 0.23536, 0.012463

I'm not sure what I'm doing wrong, so if anyone could help me with this, I'd greatly appreciate it.
